ADJUSTABLE CONNECTION FOR SWITCH-POINTS.

Specification of Letters Patent.

Patented July 28, 1908.

Application filed October 24, 1907. Serial No. 398,996.

To all whom it may concern:

Be it known that I, WILLIAM F. Bossnnr,

a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented'cer'tain new and useful Improvements in Adjustable Connections for Switch-Points; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference markedthereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustable connections for switch points in relation to the stock or main rails of a railway in connectionwith the operating pipe lines or-rods for operating signals actuated simultaneously with the movement of the switch points. In all so-called interlocking arrangements of switch points or signals operated in connection with a block system, a precise amount of elfective and ineffective movement is necessary in order to bring switch points or signals to their exact positions to accomplish the interlocking of the same.

The invention comprises further means whereby the operative mechanism for throwing the bar which connects the switch points may be suitably housed, thereby preventing ice, cinders or other foreign matter from lodging about thesurfaces of the moving parts of the apparatus and which would interfere with the efiective operation of the parts.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims. a

My invention is illustrated in the accompanying drawings, in which :Figure 1 is a plan view showing the application of the invention to switch points of a railway. Fig. 2 is a longitudinal sectional view through the housing of the apparatus and adjustable elements contained therein. Fig. 3 is a cross sectional view on line 33 of Fig. 2. Fig. 4 is a detail view of anadjusting nut. Fig. 5

is a side view of the details shown in Fig. 4. Figs. 6 and 7 show a face and edge view of an adjusting nut, and Fig. 8 is a sectional view showing a modification of my invention in which angular outlined nuts are utilized instead of semi-spherical ones, shown in Fig. 2 of the drawings.

Reference now being had to the details of the drawings by letter, A designates the body portion of a casing which may be of any suitable shape, either round or angular, and is provided with a lateral extension A, shown clearly in Figs. 2 and 3 of the drawings, and said lateral extension is provided with a longitudinal groove or recess B formed in the upper surface thereof and is adapted to receive headed bolts C assed through registering apertures in the ottom of said recessed portion of the extension of the casing and also the switch bar D, which latter is adapted to fasten to the switch points D in the manner shown in Fig. 1 of the drawings, whereby the latter may be thrown simultaneously in corresponding directions. Suitable burs or nuts C are fitted upon the threaded end of said bolt, whereby the switch bar may be securely held in place. The end of the body portion of said casing, which in the drawings 1s shown of cylindrical form, has enlarged or chambered portions designated respectively;

by letters E and E and the outer portion of the innersurface of each chamber is provided with screw threads F for the reception of the threaded cap G and an extension cap G reipectively, which caps have exterior threads for engagement with said threads F. The

central portion of the casing A has a con-.

tracted opening A parallel with the longitudinal recess in the lateral projection A andthrough which central opening a rod or bar I is adapted to pass and which latter is to be connected-with the mechanism for operating signals, etc. Said rod I is threaded at one end to receive the adjusting nuts K and K which in the drawings are shown as semispherical and provided with interior threads, the convexed surface of said nuts being ada ted to bear against a concaved abutment I sur ace L intermediate the mar inal ends of said contracted aperture and the threaded.

portion of the casing, as shown clearly in Fig. 2 of the drawings. M and M designate two locking nuts mounted upon threaded rod I, I

the former of which locking nuts is provided with annular ribs m upon opposite facesthereof, the inner of said ribs being adapted to bear against an annular rib 7c formed upon the flat outer surface of the adjusting nut K. Said extension cap G has an annular flange G adapted to abut against the adj acer'itendremoval of one or the other of the caps.

formed therein to receive the rod I.

of the casing with which the extension cap has threaded connection. Said extension cap G has a chambered portion to allow for the adjustment of the nuts K and M located therein and has a contracted opening 0 N designates a nut which is centrally apertured as at N to receive the rod I and has threaded connection with the circumference of the extension cap G and intermediate said nut N and a recessed portion formed in the outer end of the extension cap a suitable gland P is mounted, and intermediate the inner end of said gland and the bottom of the recess in which the same is located a suitable packing P is positioned to exclude any chance of moisture entering the casing.

In Fi 8 of the drawings, I have shown a sectional view of a slight modification of my invention, in which angular outlined nuts T are utilized instead of the semi-spherical nuts illustrated in Fig. 2 of the drawings and in said modification the bearing or abutment surfaces of the casing are parallel with the faces of the nuts.

It will be noted from the foregoing, when taken in connection with the drawings, that a double chamber is thus formed at one end of the casing, one com artment of the chamber being adapted for t e reception of the adjusting and lock nuts, while the other compartment forms a stuffing box in which the gland is mounted.

By the rovision of the apparatus shown and described, it will be noted that the threaded end of the rod which is adapted to be connected to the signaling apparatus is confined within the housin as shown in such a manner as to exclude tI1e admittance of dirt or any other foreign matter which might prevent injury to any parts of the apparatus, the rod passing through a suitably packed gland, the parts being readily adjusted by qtjm 1e caps G and G being provided with chambered portions will allow the adjusting and lock nuts to be moved freely in one direction or the other. These chambers, it will be understood, are provided for the purpose of excluding the admittance of anv foreign matter which might interfere wit the adjustment of the bar with relation to the switch points and signaling mechanism and will admit of ready inspection and readjustment.
